摘要
采用流动注射分析-分光光度法测定氰离子的质量浓度.设计了氰化物紫外光谱在线检测系统.结果表明:在紫外光谱216nm波长处,光的吸收最大,ρ(CN-)=1mg/L～70mg/L时,吸光度满足良好的线性,测量精度可达1mg/L.
The ultraviolet photoelectric measurement system of using flowing injection analysis and ultraviolet spectrophotometry directly is applied to detect cyanide in solutions.The results show that opties absorbency is biggest,the absorbency curve of the ultraviolet spectrum is 216 nm.When the cyanide ion concentration is between 1 mg/L to 70 mg/L the precision is 1 mg/L.
